A 57-year-old male patient presented with history of recurrent hematuria. Axial T2 WI (a) showed an intra-vesical soft tissue masses arising from left lateral and left postero-lateral bladder wall expressing intermediate signal intensity with no interruption of the hypointense underlying muscle layer. Axial ADC map (b) showed low SI of the lesion with ADC value = 0.8 × 10−3 mm2/s, consistent with high-grade tumor. Axial DW-MRI (b1000) (c) showed restricted diffusion of the masses with intact underlying low SI muscle layer. Axial post contrast T1WI FAT-SAT (d) showed early enhancement of the masses with intact underlying muscle layer and preserved submucosal linear enhancement. Time-intensity curve (e) showed grade 3 curve with early enhancement and rapid washout. Multiparametric MRI features suggest high-grade stage T1 non-muscle-invasive urinary bladder carcinoma. Microscopic image of histopathology (f) demonstrated high-grade urothelial carcinoma which confirm the multiparametric MRI finding
